I don't know if you found it
Whether it is in learning or at work
Or walking, fitness, or brushing up
Headphones have gradually become
An essential part of our daily lives
We are used to wearing headphones
Isolate yourself briefly from the whole world
Get the relaxation of the mind
However, many people use headphones when they are used
But it ignores the damage of headphones to the ear
How to choose headphones? Look at the doctor together
Wear headphones for a long time
What kind of damage can there be to hearing?
Our ears
It consists of three parts: the outer ear, the middle ear and the inner ear
The outer ear accepts sounds from the outside
Causes vibrations of the eardrum along the ear canal
Transmit the sound to the inner ear
It is then transmitted through the auditory nerve to the auditory center of the brain
So I heard the sound
An important cause of hearing loss is noise
Noisy hearing loss can be divided into chronic and acute
Acute injuries are
Strong noise at close range and suddenness
Chronic, on the other hand, is long-term exposure
Causes chronic hearing impairment
For example, wear headphones for a long time
Sound pressure is centrally transmitted to the eardrum
It is very easy to cause auditory fatigue
And due to long-term overdose of stimulation
Causes damage to peripheral receptors
Causes tinnitus, hyperauthiasis, and ear pain
Even hearing loss
American scientists back in 1998
For teenagers in the age group of six to nineteen
A survey was conducted
Fifteen percent of them were found to have symptoms of hearing loss
And that has a lot to do with their long-term use of headphones
In-ear headphones and headphones
Which is better?
Advantages of in-ear headphones
It is relatively small in size and easy to carry
Because it is in tight contact with the ear canal
Therefore, the sound insulation effect of in-ear headphones is better
And it does not come off easily
The disadvantages of in-ear headphones are also
It is relatively tight to the ear canal
Sound insulation although good
But long hours of sound stimulation
May cause eardrums, ossicles, etc
Damage to the sound conduction system
Causes tinnitus and even hearing loss
Also, plug the headphones into the ear canal for a long time
It is also easy to breed bacteria and cause infections
There are many types of headphones
With a sense of personalization and fashion
And the sound quality of headphones is generally better
It can bring users a better listening experience
Its disadvantage is that the sound insulation effect is poor
And the volume is relatively large, it is not convenient to carry
If worn for a long time, compress the ear
This may cause ischemia in the ear and cause discomfort
Each headset has its pros and cons
When we choose headphones
It can be based on our needs
When wearing headphones
Be sure to pay attention to the ear
Place on the inside of the inner edge of the headset
Avoid putting on headphones
Press against the ear
When wearing in-ear headphones
The first thing to do is to distinguish between the left and right sides
When worn
You can pull the earlobe down a bit
Widen the ear canal
Then gently put the headphones with your thumb
Push to the right part of the ear canal
Safety precautions for wearing headphones
WHO recommends when using headphones
The volume should generally not exceed 60% of the maximum volume.
It is best to adjust to a lower level so as not to overstimulate the ears
No more than 60 minutes a day is relatively safe
It is advisable to listen intermittently so that the ears can be fully rested
The amount of time you put on your headphones each time
Generally, do not exceed half an hour
No matter what type of headphones
After wearing it for a long time, the stimulation of strong sounds will be caused
Damage to the eardrum, ossicles, and nervous system
And this long-term damage
In general, it is not easy to recover
Therefore, wearing headphones must have a degree
We try not to wear headphones when we sleep
If the ear of the headset is pressed against the pillow
Damages the pinna and aggravates irritation of the eardrum
If the headset has a rustling sound or only one side has sound
It is no longer suitable for the use of the headset
If you continue to use
Prolonged periods of time may affect the balance of hearing
Also when crossing the road and cycling
Also try not to wear headphones, otherwise it is very easy to cause danger
